Abstract

Total, free and esterified cholesterol were measured in the plasma, high density lipoproteins, low density lipoproteins, and total cholesterol in the very low density lipoproteins of 141 pairs of adult white male twins. Free cholesterol in plasma, high density lipoproteins and low density lipoproteins had significant genetic variance. Esterified cholesterol had greater total variance in dizygotic than monozygotic twins, interpreted as evidence for greater environmental influences on the two types of twins. After bias due to unequal environmental effects on the two types of twins was removed, there was no significant genetic variance for any esterified fraction of cholesterol.

摘要

对141对成年白人男性双胞胎的血浆、高密度脂蛋白、低密度脂蛋白中的总胆固醇、游离胆固醇和酯化胆固醇,以及极低密度脂蛋白中的总胆固醇进行了测量。血浆、高密度脂蛋白和低密度脂蛋白中的游离胆固醇具有显著的遗传方差。酯化胆固醇在异卵双胞胎中的总方差大于同卵双胞胎,这被解释为环境对这两种双胞胎的影响更大的证据。在消除了由于环境对两种双胞胎的影响不平等所导致的偏差后,胆固醇的任何酯化部分均无显著的遗传方差。
